Aside from stop light to stop light acceleration, there isn't any benefit to swapping the PRV V-6 engine out of the DMC. The DeLorean engine is reliable and easy to maintain. The myth is that the PRV in the DeLorean is a POS...not true. Renault Formula One Racing won many races around the world with PRV racing variant. That engine redlined at 10,000 RPM and made over 490 HP. The early PRV engines in the Volvo 260s from the mid '70s had issues surrounding oil flow delivery around the cams. PRV factory engineers over in France corrected the issue long before the DMC ever made it into production. Another myth surrounds the BOSCH K-Jetronic fuel injection in the DeLorean PRV engine. The fuel system is reliable and maintenance free, however it will fail if the car is not driven...plain and simple. Think about those beautiful supermodels...they get pissed off, temperamental, demanding, and cranky if you quit paying attention to them...if you find one that isn't...give me her name. The DeLorean car BOSCH fuel system does not like long term storage and will act the same way. Long term, incorrect storage will wreak havoc on ANY car. E.G. The same BOSCH fuel injection system on the DeLorean is also on late model Lamborghini Countach...twice over. Two fuel distributors, two cold start injectors, two accumulators etc. The Lamborghini, a very fast, unrefined, unreliable, pain in the ass to drive and operate, and they usually have very low miles on the odometer. There is an owner near me with 90,000 miles on his Countach, however he has taken the effort to drive the car almost everyday. He explained that most of the Lambo car owners let them sit for long periods without starting them or adding a fuel stabilizer. The same problems on the Countach list are asked here on the DML. The issue arises from deteriorated fuel system from improper long term storage. The PRV engine is a strong motor. The DeLorean specialists can clarify any of your questions about high mileage capabilities. To date I do not remember reading anywhere on this list or in DeLorean World magazine about engine failure, aside from overheating the engine and warping the heads & damaging the headgaskets...that is a direct result of a damaged cooling system (bad hoses, belts, radiator, waterpump) and not changing the oil every 3,000 miles with a correct filter. The no start issues, incorrect idle, etc., the multitude of problems about DeLorean engine reliability on this DML list is attributed to incorrect repair, incorrect parts, incorrect long term storage, incorrect methods of awakening a car back to life after long term storage, etc., and not maintaining the car properly...unfortunately many owners are driving around with an incorrect oil filter, and a worn out, 21 year old, corroded, cooling system with duct tape keeping the hoses together. Not worry because the DeLorean specialists have just about every part for the DeLorean available. Here are some web pages over in Europe devoted to the PRV engine: http://www.simon-auto.de/site/10.html Here you can upgrade the engine's performance to suit your needs...if that is what you're after. http://www.douvrinprv.com/ The second page has many links to different suppliers and high performance dealers. To summarize, the PRV engine issues are not some inherent design flaws or poor planning by the Renault engineers...the owners issues you read & hear about here on the DML arise from lack of proper maintenance & a general unfamiliarity with the engine operation and basic maintenance requirements. If you spend some time reading about the engine (reviewing your budget & finances as well) and read how to maintain the car properly, buying the correct parts from a DeLorean specialist will keep a smile on your face.
